Art Assylum P1 Phaser Electronics.

Anyone dive into these electronics? I have mine apart and diggin into it. Trying to add some other options.

Trying to figure out what the two tabs on the side are for. They happen to line up with the notch in the side of the phaser at the side seam. I am guessing they are for testing at assy.

What i want to do is:

Get control of a pager motor from the trigger switch in the P1. The motor is located in the P2 part of the phaser with its own batteries. My first stab was to put its own switch in the P2 off the trigger but thought there may be a better idea out there.
